TACHOMETER
The tachometer indicates engine speed in
revolutions per minute (rpm). Do not rev
the engine into the red zone
1.
CAUTION
When engine speed approaches the red
zone, reduce engine speed. Operating
the engine in the red zone may cause
serious engine damage.
ENGINE COOLANT TEMPERATURE
GAUGE
The gauge indicates the engine coolant
temperature. The engine coolant tempera-
ture is within the normal range
1when
the gauge needle points within the zone
shown in the illustration.
The engine coolant temperature varies
with the outside air temperature and driv-
ing conditions.
CAUTION
If the gauge indicates coolant tempera-
ture near the hot (H) end of the normal
range, reduce vehicle speed to decrease
temperature. If the gauge is over the
normal range, stop the vehicle as soon
as safely possible. If the engine is over-
heated, continued operation of the ve-
hicle may seriously damage the engine.
For additional information, refer to “If
your vehicle overheats” in the “In case
of emergency ” section of this manual
for immediate action required.

Operating tips
∙ Keep the windows closed while the airconditioner is in operation.
∙ Af ter parking in the sun, drive for 2 or 3 minutes with the windows open to
vent hot air from the passenger com-
partment. Then, close the windows.
This allows the air conditioner to cool
the interior more quickly.
∙ The air conditioning system should be operated for approximately 10 minutes
at least once a month. This helps pre-
vent damage to the system due to lack
of lubrication.
∙ A visible mist may be seen coming from the ventilators in hot, humid conditions
as the air is cooled rapidly. This does not
indicate a malfunction.
∙ If the engine coolant temperature gauge indicates engine coolant tem-
perature over the normal range, turn
the air conditioner off. For additional in-
formation, refer to “If your vehicle over-
heats” in the “In case of emergency”
section of this manual. ∙ When Remote Engine Start (if so
equipped) is activated, the manual cli-
mate control system will default to the
last used heating or cooling mode.
AIR FLOW CHARTS
The following charts show the button and
dial positions for MAXIMUM AND QUICK
heating, cooling or defrosting. The
air
recirculation button should always be in
the off position for heating and defrost-
ing.
Monitor, climate, audio, phone and voice recognition systems4-33

∙ When the climate system is in auto-matic operation and the engine coolant
temperature and outside air tempera-
ture are low, the air flow outlet may de-
fault to defroster mode for a maximum
of 2 minutes 30 seconds. This is not a
malfunction. Af ter the engine coolant
temperature warms up, the air flow out-
let will return to foot mode and opera-
tion will continue normally.
∙ When the outside and interior cabin temperatures are moderate to high, the
intake setting may default to turn off air
recirculation to allow fresh air into the
passenger compartment. You may no-
tice air flow from the foot mode, bi-level
mode, or side demist vent outlets for a
maximum of 15 seconds. This may oc-
cur when the previous climate setting
was turned off. This is not a malfunction.
Af ter the initial warm air is expelled, the
intake will return to automatic control,
the air flow outlet will return to previous
settings, and operation will continue
normally. To exit, press any climate con-
trol button.
∙ Keep the moonroof (if so equipped) closed while the air conditioner is in op-
eration. ∙ If you feel that the air flow mode you
have selected and the outlets the air is
coming out do not match, select
the
mode.
∙ When you change the air flow mode, you may feel air flow from the foot out-
lets for just a moment. This is not a
malfunction. The air conditioner system in your NISSAN
vehicle is charged with a refrigerant de-
signed with the environment in mind.
This refrigerant does not harm the
earth’s ozone layer.
Special charging equipment and lubricant
is required when servicing your NISSAN air
conditioner. Using improper refrigerants or
lubricants will cause severe damage to
your air conditioner system. For additional
information, refer to “Air conditioner sys-
tem refrigerant and oil recommendations”
in the “Technical and consumer informa-
tion” section of this manual.
It is recommended that you visit a NISSAN
dealer to service your “environmentally
friendly” air conditioner system.
WARNING
The air conditioner system contains re-
frigerant under high pressure. To avoid
personal injury, any air conditioner ser-
vice should be done only by an experi-
enced technician with proper
equipment.

∙ Do not use the cruise control on slip-pery roads.
∙ Snow can trap dangerous exhaust gases under your vehicle. Keep snow
clear of the exhaust pipe and from
around your vehicle.
ENGINE BLOCK HEATER (if so
equipped)
Engine block heaters are used to assist
with cold temperature starting.
The engine block heater should be used
when the outside temperature is 20°F (-7°C)
or lower.
WARNING
∙ Do not use your engine block heaterwith an ungrounded electrical system
or a 2-pronged adapter. You can be
seriously injured by an electrical
shock if you use an ungrounded
connection.
∙ Disconnect and properly store the en- gine block heater cord before starting
the engine. Damage to the cord could
result in an electrical shock and can
cause serious injury. ∙ Use a heavy-duty 3-wire, 3-pronged
extension cord rated for at least 10 A.
Plug the extension cord into a Ground
Fault Interrupt (GFI) protected,
grounded 110-VAC outlet. Failure to
use the proper extension cord or a
grounded outlet can result in a fire or
electrical shock and cause serious
personal injury.
To use the engine block heater: 1. Turn the engine off.
2. Open the hood and unwrap the engine block heater cord.
3. Plug the engine block heater cord into a grounded 3-wire, 3-pronged exten-
sion cord.
4. Plug the extension cord into a Ground Fault Interrupt (GFI) protected,
grounded 110-volt AC (VAC) outlet.
5. The engine block heater must be plugged in for at least 2–4 hours, de-
pending on outside temperatures, to
properly warm the engine coolant. Use
an appropriate timer to turn the engine
block heater on. 6. Before starting the engine, unplug and
properly store the cord to keep it away
from moving parts.
5-182Starting and driving

CAUTION
∙ Do not push start this vehicle. Thethree-way catalyst may be damaged.
∙ Continuously Variable Transmission (CVT) models cannot be push-started
or tow-started. Attempting to do so
may cause transmission damage. If your vehicle is overheating (indicated by
an extremely high temperature gauge
reading), or if you feel a lack of engine
power, detect abnormal noise, etc. take the
following steps.
WARNING
∙ Do not continue to drive if your vehicle
overheats. Doing so could cause en-
gine damage or a vehicle fire.
∙ To avoid the danger of being scalded, never remove the radiator cap while
the engine is still hot. When the radia-
tor cap is removed, pressurized hot
water will spurt out, possibly causing
serious injury.
∙ Do not open the hood if steam is com- ing out.
1. Move the vehicle safely off the road, ap- ply the parking brake and move the
shif t lever to P (Park).
Do not stop the engine.
2. Turn off the air conditioner. Open all the windows, move the heater or air condi-
tioner temperature control to maxi-
mum hot and fan control to high
speed. 3. Get out of the vehicle. Look and listen
for steam or coolant escaping from the
radiator before opening the hood. (If
steam or coolant is escaping, turn off
the engine.) Do not open the hood fur-
ther until no steam or coolant can be
seen.
4. Open the engine hood.
WARNING
If steam or water is coming from the
engine, stand clear to prevent getting
burned.
5. Visually check drive belts for damage or looseness. Also check if the cooling
fan is running. The radiator hoses and
radiator should not leak water. If cool-
ant is leaking, the water pump belt is
missing or loose, or the cooling fan
does not run, stop the engine.
WARNING
Be careful not to allow your hands, hair,
jewelry or clothing to come into contact
with, or get caught in, engine belts or
the engine cooling fan. The engine cool-
ing fan can start at any time.

CHECKING ENGINE COOLANT
LEVEL
Check the coolant levelin the reservoir
when the engine is cold. If the coolant
level is below the MIN level
B, add coolant
to the MAX level
A.
If the reservoir is empty, check the coolant
level in the radiator when the engine is
cold. If there is insufficient coolant in the
radiator, fill the radiator with coolant up to
the filler opening and also add it to the
reservoir up to the MAX level
A. Start the
engine and allow the engine coolant tem-
perature gauge to rise until it reaches nor- mal operating temperature. For additional
information, refer to “Engine coolant tem-
perature gauge” in the “Instruments and
controls” section of this manual. Turn off
the engine once the engine coolant tem-
perature has reached normal operating
range. Allow the engine coolant to cool to
ambient temperature. Recheck the cool-
ant level in the reservoir and add coolant to
the MAX level if necessary.
This vehicle contains Genuine NISSAN Long
Life Antifreeze/Coolant (blue). The life ex-
pectancy of the factory-fill coolant is
105,000 miles (168,000 km) or 7 years. Mixing
any other type of coolant or the use of
non-distilled water will reduce the life ex-
pectancy of the factory-fill coolant. For ad-
ditional information, refer to the "Mainte-
nance and schedules" section of this
manual.
For additional information on the location
of the engine coolant reservoir, refer to “En-
gine compartment check locations” in this
section.
If the cooling system frequently requires
coolant, have it checked. It is recom-
mended that you visit a NISSAN dealer
for this service.
CHANGING ENGINE COOLANT
A NISSAN dealer can change the engine
coolant. The service procedure can be
found in the NISSAN Service Manual.
Improper servicing can result in reduced
heater performance and engine over-
heating.
WARNING
∙ To avoid the danger of being scalded,
never change the coolant when the
engine is hot.
∙ Never remove the radiator cap when the engine is hot. Serious burns could
be caused by high pressure fluid es-
caping from the radiator.
∙ Avoid direct skin contact with used coolant. If skin contact is made, wash
thoroughly with soap or hand cleaner
as soon as possible.
∙ Keep coolant out of the reach of chil- dren and pets.
Engine coolant must be disposed of prop-
erly. Check your local regulations.
